To the Editor:—
The correspondent is justified in criticizing the expression "absolutely irregular" as applied to the heart rhythm. It would have been better to say "quite irregular from numerous extrasystoles." "Perpetual arrhythmia," "complete irregularity," if used at all nowadays are usually meant to imply auricular fibrillation. I have no quarrel with him over his contention that an "irregularity" can generally be diagnosed without the electrocardiogram. This should be attempted always. The electrocardiogram should be confirmatory or corrective. This was the procedure in the case reported and I regret that there was not greater care in the use of terms.
